FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 784,528, dated March14, 1905.

Application filed December 24, 1903. Serial No. 186.464.

1'0 (all 'whont z'tvnmy concern.-

Be it known that 1, THOMAS P. AMBROSE, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Fountain-Pens, ofwhich the following is a specification.

My invention relates to improvements in that class of fountain-pens inwhich the fountain is an india-rubber or other flexible elastic tube.

The object of my invention is to produce a simple, convenient,economical, and durable fountain-pen provided with an ink-reservoirwhich can be easily filled without removing it from the frame orpen-feed to which it is attached.

My invention consists in providing a holder with a flexibleink-reservoir held within a frame having open sides and adapted to becovered by a sleeve.

My invention also consists in the parts and combination and arrangementof parts, as herein described and as particularly pointed out in theclaim.

In the drawings which serve to illustrate my invention, Figure I is aside elevation showing the parts assembled in position to carry in thepocket. Fig. 2 is a side elevation showing the cap removed from over thepen-point and placed upon the opposite end of the holder. Fig. 3 is aside elevation showing the sleeve moved from its normal position toexpose the flexible reservoir. Fig. 4 is a side elevation of the framewhich incases the reservoir and carries the sleeve. Fig. 5 is a sideelevation of the sleeve. Fig. 6 is a side elevation of the cap. Fig. 7is a side elevation of the pen-feed and flexible ink-reservoir attachedthereto.

My improved device is preferably constructed substantially as follows:The slotted frame 1, as shown in Fig. 4, is cylindrical in shape and isadapted to receive and hold the flexible ink-reservoir 2, pen-feed 3,and penpoint 4, as shown in Fig. 3, and to be incased in the cap 5 andsleeve 6, as shown in Fig. 1. An annular boss or band 7 is formed on thesleeve between one end and the slotted portion to form a stop for thecap and sleeve and to produce a uniform surface for the holder. Thepen-feed 3 and ink-reservoir2 afe secured together by frictional contactand they are likewise held in the frame 1 in the same manner. Thepen-point 4 is supported in its place in any desired manner, fittingbetween the wall of the frame and the pen-feed. The penfeed 3 ispreferably formed with a large cavity 9, as shown by dotted lines, butmay be provided with asmall passage for the ink, as desired. By having alarge cavity there is less danger of clogging than otherwise. Thepenfeed and ink-reservoir may be permanently or removably secured withinthe frame. I prefer to secure them permanently. IV hen it is desired tofill the ink-reservoir, simply insert the pen into theink-bottle orother receptacle and compress the elastic reservoir between the thumband linger and release same. This will produce the necessary suction andaccomplish the desired result. Then slip the sleeve into position on theframe as shown in Fig. 2, and the pen is ready for use. The cap may becarried as shown in Fig. 2 when writing and at other times as shown inFig. 1. It will thus be seen that by my improved device I am enabled toreink the reservoir easily and quickly by merely shifting the sleeve, asshown in Fig. 3, compressing the bulb, and then readjusting the sleeveto the position shown in Fig. 2. In order to hold the sleeve fromaccidentally slipping out of place, I provide a stud 10 upon the frameand a recess 11 upon the sleeve, so that when the sleeve is adjustedinto position the stud will be forced into the recess, and thereby holdthe sleeve from rotary movement on the frame. I construct the sleeve ofshorter length than the frame, so that the cap may be held in theposition shown in Fig. 2 when the pen is being used.

I claim I and said ink-reservoir and engaging said stud, As a new andimproved article of manufacand the cap 5, all combined in the manner andI0 tuxgmla ffiuntaillrpen cciiislistinhg' lof liOhe sl$tted I for thepurposes specified. tu u at 'rame provic ec Wit t 1e oss anc 5 the stud10, the flexible ink-reservoir 2 hav- THOMAS AMBROSE ing the pen-feed 3secured in said frame, the recessed sleeve 6 adjustably secured on saidframe, covering the slots in said tubular frame l l/Vithess'es:
